UNITED STATES PATsNroFFicE CIGARETTE Maurice X. C. Weinberger, Brooklyn, N. Y., assignor to Self Extinguishing Cigarette Corporation, a corporation of New York Application April 7, 1933, Serial No. 664,888 3 Claims. (Cl. 131-52) My invention relates to an improvement in Figs. 1 and 2 and showing another modified .form cigarettes, and has particular reference to the of cigarette, which embod'es the present invenpreparation of the envelope or container, herein tion and in which the paper of Fig. 3C is employed e called the paper, of the cigarette.

The imperforate transverse portions of the superimposed sheet of paper 2" assume the form of a centric bands, corresponding to the concentric bands 4 and 4 upon completion of the cigarette rolling operation, that they, together with the particles of tobacco adhering thereto, serve, like the concentric bands 4 and 4 with their adhering particles of tobacco, to render the cigarette selfextinguishing. Instead'of employing the strips of paper 2 or the strips of paper 2 or the sheet of paper 2 as and for the purpose hereinbefore described, a cigarette, of the form shown in Fig. 4 and which embodies the present invention, may be produced with the cigarette paper 2" shown in Fig. 3C. As to the cigarette paper 2", it is to be noted that the agglutinating substance, as shown at 6, is applied directly to and extends transversely of the tobacco-receiving surface of the paper relatively near one end thereof. Upon preparatory to the cigarette-rolling operation, particles of the tobaccobecome attached, through the medium of the agglutinating substance, directly to that paper and present, in association with the aggluplurality of parallel contlnating substance, 2. band 4" in the finished cigarette as shown in Fig. 4, which band renders the cigarette self-extinguishing at and in the vicinity of the band-like zone which is occupied by the adhering tobacco particles.

The term band as used in this specification implies a stripe of agglutinating substance on the inner surface of the wrapper of a cigarette.

Aside from the different forms of the invention herein shown and described, other modifications may be employed without departing from the spirit of the invention or'the scope of the following claims.

What is claimed is:

1. A cigarette having on the inside of its wrapper a band. of agglutinating substance which attaches certain of the tobacco fibres to the wrapper.

2. A cigarette comprising a filler and an envelope embracing said filler, and having attached to its inner wall particles of the filler material, said particles being disposed in a band-like zone intermediate the ends of said envelope.

3. A cigarette comprising a filler and an envelope embracing said filler and having attached to its inner wall particles of the filler material, said particles being disposed in a band-like zone intermediate the ends of said envelope and intermingled with the remaining portion of the filler content.
